摘要：

A new ultrathin multilayer film consisting of polyoxometalate (POM) cluster Na-12[P2W15O56](.)18H(2)O (P2W15) and polyallylamine hydrochloride (PAH) were fabricated on quartz and ITO substrates by layer-by-layer self-assembly method. The multilayer films, PSS/PAH/(P2W15/PAH)(n) were characterized by UV-vis spectra, cyclic voltammetry (CV) and chronoamperometric (CA) measurements. The electrochromic film exhibits both suitable response time and low power consumption due to the presence of lacunary polyoxometalate, providing valuable information for exploring the potential application of polyoxometalate-based electrochromic materials.
